How do you tame that monkey-brain that's keeping you up at night? Some folks swear by white noise, which works based on ears, brain and science something-something.
This high-end LectroFan model features an impressive 20 different sound options. You can set it to run all night, or flip a switch for a 60-minute timer. Use code CNETLFN to knock the price down to $30. (It runs $50 at Amazon, where it has over 4,000 reviews and a 4.6-star average rating.)
Could you just use your phone and a white-noise app to accomplish the same thing? Yep! But many of them are subscription-based, and who wants to futz with your phone when you're trying to sleep? There's something to be said for a dedicated device with analog switches.
